A softly lit bedside table in a calm, modern bedroom at dusk, photographed in wide landscape format with shallow depth of field. In the foreground, a matte white shaker bottle sits beside a tall frosted glass of creamy, pale vanilla-colored protein shake, with a few condensation droplets catching warm light. Next to the glass rests a slim fitness band on a dark charcoal fabric strap, its small LED glowing a gentle green, lying casually on a light oak wooden surface. A small scoop of fine white protein powder rests on a ceramic dish nearby, with a light dusting of powder on the wood.

In the soft-focus background, a neatly made bed with oatmeal-colored linen bedding and a textured knit throw blanket. A sheer curtain filters the last peach and lavender light of evening from a large window. A small potted olive branch in a terracotta vase and a closed paperback book add a quiet editorial touch. A bedside lamp with a warm, cream-colored shade casts a golden glow across the scene and creates gentle highlights on the glass.

The palette is muted and harmonious: warm cream, soft sand, oatmeal beige, faint sage green accents, and touches of dusty lavender in the window light. The mood is peaceful, reassuring, and clean, like a contemporary wellness magazine or a trendy health journal feature. Lighting is natural and cinematic, with soft shadows and a subtle film-like grain. The composition follows the rule of thirds, with the shake and band on the left third and open negative space on the right for headline overlay. Minimalist, Scandinavian-inspired styling, high-end lifestyle photography, crisp details, and a tranquil, premium editorial feel.

就寝前にカゼインを摂っても睡眠は乱れない――WHOOP データが示す結果

BY DR. GYMBRO · 2026年10月29日

40 g のカゼインシェイクを就寝前に摂取しても、総睡眠時間・睡眠効率・安静時心拍数・HRV などに有意な影響は見られませんでした。アルファラクトアルブミンや炭水化物でも同様の結果です。ただし、どの条件も睡眠を改善したわけではありません。本稿ではデータの示すこと、研究の限界、そして夜間のシェイクを控えた方が良い人の特徴をまとめます。
